, due each Friday at midnight, starting the second week. We will use for homework submission, with the details on . We will have a late day policy on homeworks. Each student has one late day, i.e., you may submit one homework (except for homework 0) up to 24 hours late. Always reach out if you're facing unusual disruptions to your classwork. You are allowed, even encouraged, to work on the homework in small groups, but you must write up your own homework to hand in. Each question on the homework will be graded on a scale of {0, 1, 2}. . The format is a timed online 75 minute exam, at the end of the 3rd week. The midterm quiz covers chapters 1–3, and the concept of (DCP). . The format is a 24 hour take home exam, scheduled for the end of the last week of classes. You can take it during any 24 hour period over a multi-day period we'll fix later. We can arrange for you take it earlier (as a beta tester, and only if you really need to) but not later. The final exam will .Homework 20%, midterm 15%, final exam 65%. These weights are approximate; we reserve the right to change them later.
Good knowledge of linear algebra (as in ) and probability. Exposure to numerical computing, optimization, and application fields helpful but not required; the applications will be kept basic and simple.
You will use to write simple scripts, so basic familiarity with elementary Python programming is required. We will be supporting other packages for convex optimization, such as (Julia), (Matlab), and (R). In particular, the final exam will .
Concentrates on recognizing and solving convex optimization problems that arise in applications. Convex sets, functions, and optimization problems. Basics of convex analysis. Least-squares, linear and quadratic programs, semidefinite programming, minimax, extremal volume, and other problems. Optimality conditions, duality theory, theorems of alternative, and applications. Interior-point methods. Applications to signal processing, statistics and machine learning, control and mechanical engineering, digital and analog circuit design, and finance.
This course should benefit anyone who uses or will use scientific computing or optimization in engineering or related work (e.g., machine learning, finance). More specifically, people from the following departments and fields: Electrical Engineering (especially areas like signal and image processing, communications, control, EDA & CAD); Aero & Astro (control, navigation, design), Mechanical & Civil Engineering (especially robotics, control, structural analysis, optimization, design); Computer Science (especially machine learning, robotics, computer graphics, algorithms & complexity, computational geometry); Operations Research (MS&E at Stanford); Scientific Computing and Computational Mathematics. The course may be useful to students and researchers in several other fields as well: Mathematics, Statistics, Finance, Economics.

The document provides solutions to homework problems about positive semidefinite cones, monotone nonnegative cones, level sets of convex and concave functions, and families of concave utility functions. For positive semidefinite cones, explicit descriptions are given for n=1,2,3 involving matrix coefficients and inequalities. For monotone nonnegative cones, it is shown to be a proper cone and ...

this holds for k = 2; you must show it for arbitrary k.) Hint. Use induction on k. Solution. This is readily shown by induction from the definition of convex set. We illustrate the idea for k = 3, leaving the general case to the reader. Suppose that x1,x2,x3 ∈ C, and θ1 + θ2 + θ3 = 1 with θ1,θ2,θ3 ≥ 0. We will show that y =
